Hello, I am using Tread but I do not sync the routes. I just connect it to the PC and transfer the GPX to the SD card. Weather radar works and traffic information. All good. And the route planner on the Garmin is not too bad either. When I plan my trips/routes I use the planner of MyRoute on the computer. Save it and drive. I anyway spend time to generate the routes and after they are ready they will be pushed to the XT3. I do not let the Tread app sync because there can be surprises but I do not need to do this often. And in case I have no option to transfer data I use the Garmin route planner.
